The documents herein regard the Mattel Electronics Intellivision project ranging from its inception in 1977 until the end of Chandler's involvement with the company in 1983.
This undated document contains a letter and a check for $2.50 towards an Intellivision cartridge, signed by George Plimpton. These would have been issued in the 1981-1983 time period to new owners of the Intellivision as part of a promotional program.
